Turkish archaeologists excavating a harbor site on the European side of the Bosphorus have unearthed a 1,200-year-old wooden object which they claim is the ancient equivalent of a tablet computer. The device was a notebook and tool — in one.

The Byzantine invention was found within the remains of one of the 37 ships unearthed in the Yenikapi area of Istanbul, a site which has been at the center of excavations for the past 10 years.
